The HPLC methods for analysis of N--ribitylxylidine and N-methyl glucamine were established. After optimizing the operation conditions, the principal product and main impurities were well separated. And they were determined by LC-MS. The operation condition of N--ribitylxylidine is, columniation temperature is 30℃, flow rate is 0.7mL/min, UV wave is 244nm, the mobile phase is methanol: water=40: 60 .

产物主要呈二十面体形和十面体形，结晶很好并具五次对称性。

Radioactive decay studies have found a kinds of elements can be α or β decay and the decay into another element, while the α-decay product of -α-rays became one of the deep structure of the material means of .1911, the Rutherford and others bombarded atoms with α-rays observed wide-angle deflection to determine the nuclear structure of atoms and nuclei was first proposed the term .1919 year, Rutherford and others have also found that with α-ray bombardment of nitrogen will release the nuclear protons, this is the first time Artificial realization of a nuclear reaction, after the bombardment of nuclei with the radiation caused by nuclear reaction method to become the primary means of research in nuclear.

放射性衰变研究发现了一种元素可以通过α衰变或β衰变而变成另外一种元素，而α衰变的产物——α射线又成了人们探讨物质深层结构的手段。1911年，卢瑟福等人用α射线轰击原子、观察到大角度偏折，从而确定了原子的有核结构，并首次提出原子核这一名词。1919年，卢瑟福等人又发现用α射线轰击氮核会放出质子，这是首次用人工实现的核反应，以后用射线轰击原子核来引起核反应的方法逐渐成为研究原子核的主要手段。
